You need to start by drawing a diagonal line between two corners, and that will give you two triangles. Once you have the two triangles, you can find the area of the whole shape by doubling the area of the two triangles. This of course means that you will have to do two simple equations - finding the area of the two triangles.

It's really easy to find the area of a triangle. You first need to multiply the base of the triangle, by the height. You then need to divide it by two to provide you with the whole area of the one triangle. This is bxh/2.

You need to choose any side of the triangle and use that as the base. If the triangle is a right angle triangle, then you can use one of the sides that forms the right angle. You then need to go about measuring the length of the side you have chosen as the base.

Once you've done that you need to measure the length of that base. You need to find the height of the triangle, next. The height isn't necessarily any one of the sides of the triangle. The height of the triangle will always be at a right angle (perpendicular) to the base. So find which side is the base and then measure the line that is at a right angle to it, and this will give you the value of the height.

Then just multiply the value of the base by the value of the height, and take the number that you obtained in your calculations during step five, and then divide that by two. This gives you the whole area of the triangle, and by combining the two areas you will have the area of the whole shape.
